Overview

FastAPI is one of the most efficient frameworks for building modern APIs with Python, widely used by companies like Microsoft, Uber, and Netflix due to its high performance and native support for static typing and asynchronous operations. This book provides a comprehensive guide, from installation and initial setup to the implementation of scalable and secure APIs for real-world applications. The content covers project structuring with APIRouter, advanced request handling, authentication with JWT and OAuth2, integration with PostgreSQL, MySQL, and MongoDB, and performance optimization with Redis and Memcached. It also includes essential techniques for efficient deployment on cloud services like AWS Lambda, Google Cloud Run, and Azure Functions, test automation with Pytest, and monitoring with Prometheus and Grafana. Each chapter follows the TECHWRITE 2.1 methodology, combining structured theory and practice, with explanatory code, best practices, and solutions for common errors. Whether developing REST APIs, microservices, or real-time applications with WebSockets, this book provides the necessary tools to apply FastAPI in robust and scalable projects. Ideal for developers looking to build modern APIs and optimize workflows, LEARN FastAPI: From Fundamentals to Practical Applications is a technical and objective guide for professional use of the framework.
